| Abstract(in English) | A low noise medium design is described focussing on Co-Cr-Nb films. Targeted magnetic parameters for a low noise medium (Ms～200 emu/cm^3, Hc_⊥>2500 Oe, Hc_⊥/Hk_⊥>1/3) are presumed by considering M-H loops of Co-Cr films. Only Co-Cr-Nb films with high Cr contents could satisfy these parameters when deposited with a substrate temperature of 600℃. The high deposition temperature was adopted according to an elevated transition temperature of about 500℃ at which Cr microsegregation in the film becomes enhanced. Magnetic properties of the film was also supported by a highly oriented Ti underlayer. In the crystallographic point of view, a Co-Cr-Nb film was found to have a more continuous structure in the film thickness direction than a Co-Cr-Ta film. |
